Implementation of an optical S-R flip-flop with polarization encoded light signal

Abstract

A new method is proposed to implement an optical S-R flip-flop by polarization encoded light signal, necessary optical nonlinear material and half-wave plate. In this system the real time speed of operation can be achieved, and at the time of transmission the average power of a byte remains constant. This polarization encoded flip-flop can act as a memory cell.

Role of optics in super-fast information processing

“…'Optics' has no Coulomb interaction and no cross-talk effect. So a high degree of inherent parallelism can be achieved from an 'optically run system' [1][2][3][4][5][6][7][8][9][10][11][12]. If information is coded with an optical signal it can be sent through a high electric or magnetic or through a high electromagnetic field without any kind of distortion.…”

“…After these implementation they extended the above technique for developing and 'optical logic and algebraic processor (OLAP)', and with OLAP digital processing between two images were also implemented. In the last three decades thousands of theoretical and experimental works were reported where optics were used very nicely to implement logic, arithmetic, algebraic devices [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The present author and his group proposed also several methods of such optical information processing [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…Optical bistable material, optical space light modulators, optical nonlinear materials, semiconductor optical amplifiers etc. were used very successfully to develop an optical switch [1][2][3][4][5][6][7][8]10,12]. These switches ultimately develop optical logic devices which are basic building blocks of a computer.…”

“…Based on this switching action several all-optical logic devices were proposed for implementation [3][4]. [7][8]. Figure 4 on the other hand shows an frequency encoded optical OR logic unit [10][11].…”
